“…65 Liu et al synthesized a magnetic chitosan three-dimensional biosorbent for the removal of methylene blue using agricultural waste corn stalk core as a scaffold and green crosslinking. 66 Some researchers have also used special crosslinking agents and methods to achieve non-toxic crosslinking. Wang et al synthesized a nanocomposite magnetic attapulgite using ethylene diaminetetraacetic acid (EDTA) as a crosslinking agent.…”

“…The PFO kinetic model describes the adsorption process as controlled by the diffusion step; it follows a physical adsorption mechanism (physisorption kinetics). By contrast, the PSO kinetic model describes the adsorption rate as affected by the chemical interaction between the adsorbate and the adsorbent; it follows a chemical adsorption mechanism (chemisorption kinetics) [93,94]. The kinetic parameters for MB and BR9 adsorption are shown in Table 5.…”

Methylene blue (MB) and basic red 9 (BR9) are cationic dyes that are commonly used in the dye industry and negatively affect humans and other living organisms. This study compares the performance of Indonesian rice husk (IRH) and Hungarian rice husk (HRH) as bio-adsorbents for removing MB and BR9 from aqueous solutions. Chemical content, zeta potential, and Fourier-transform infrared spectroscopy analyses were used to characterize the rice husks (RHs). Adsorption studies were performed through batch experiments involving several parameters, namely, pH, adsorbent dose, initial dye concentration, contact time, and temperature to observe the self-association (aggregation) of MB and BR9. Adsorption kinetic studies showed that maximum dye removal was achieved at a contact time of 120 min. MB and BR9 adsorption followed a pseudo-second order kinetic model, and the BET multilayer isotherm model provided a better fit to the experimental data of MB and BR9 adsorption. The IRH adsorption capacities were 15.0 mg/g for MB and 7.2 mg/g for BR9, whereas those of HRH were 24.4 mg/g for MB and 8.3 mg/g for BR9. Therefore, these RHs are potential bio-adsorbents for removing MB and BR9 from aqueous solutions.
